Q370R Pressure Vessel Steel Plate
Q370R steel boiler plate belongs to the domestic pressure vessel steel plate grade, is the boiler and pressure vessel plate with low temperature steel plate, because Q370R boiler steel plate is often default state for low-temperature impact -20 ° C delivery, so the Q370R boiler plate is called low-temperature pressure vessel steel plate.
Q370R vessel plate brand name: "Q" means yield, "370" means yield value, R means initial capital letter.
Q370R pressure vessel quality steel is used in chemical industry, petroleum, chemical equipment, deethanisation tower, CO2 absorption tower, medium-pressure flash evaporation tower, cooler, deethanisation tower, reabsorption tower, compressor casing and so on.
